Title: Facsimile radio communication system having multiple data speeds
Inventor: BERLAND KERRY S
IPC: H04N1/21
Filed: 1994-08-31
Abstract: FACSIMILE RADIO COMMUNICATION SYSTEM      HAVING MULTIPLE DATA SPEEDS     Kerry S. Berland Abstract of the Disclosure A communication system which enables conventional telephone-type facsimile apparatus to reliably and efficiently communicate over a conventional two-way voice radio communication system.  The system includes an interface unit which is connected to the facsimile apparatus and to the transceiver apparatus of the radio communication system without modification to either unit.  The interface unit transmits and receives information over the radio system in the form of a series of data packets, each containing origin address, destination address, send sequence and check digit information for optimum transmission accuracy and efficiency.  A confirmation packet of like send sequence sent by the receiving unit when received at the transmitting unit verifies transmission.  In the absence of such verification the data packet is retransmitted.  To optimize data transmission in the presence of weak signals or noise on the radio channel, the information packet speed for a link between two stations is selected adaptively as the highest available data speed which yields a predetermined maximum bit error rate.          Packets controlling access to the radio channel are sent at a common lower network packet speed, thereby providing mutual intelligibility of all devices on the channel.     Before information packets are transmitted at the higher information packet speed, the channel is reserved for a specified time period by the exchange of channel reservation packets, notifying units in radio range of the transmitter and receiver that the channel has been reserved, thereby avoiding packet collisions which might otherwise be generated by units which could not readily detect differing data speeds on the radio channel.

Title: High performance error control coding in channel encoders and decoders
Inventor: GANESAN KALYAN
IPC: H03M13/29
Filed: 1994-09-08
Abstract: ABSTRACT OF THE DISCLOSURE       An improved error control coding scheme is implemented in low bit rate coders in order to improve their performance in the presence of transmission errors typical of the digital cellular channel. The error control coding scheme exploits the nonlinear block codes (NBCs) for purposes of tailoring those codes to a fading channel in order to provide superior error protection to the compressed half rate speech data. For a half rate speech codec assumed to have a frame size of 40 ms, the speech encoder puts out a fixed number of bits per 40 ms. These bits are divided into three distinct classes, referred to as Class 1, Class 2 and Class 3 bits. A subset of the Class 1 bits are further protected by a CRC for error detection purposes. The Class 1 bits and the CRC bits are encoded by a rate 1/2 Nordstrom Robinson code with codeword length of 16. The Class 2 bits are encoded by a punctured version of the Nordstrom Robinson code. It has an effective rate of 8/14 with a codeword length 14. The Class 3 bits are left unprotected. The coded Class 1 plus CRC bits, coded Class 2 bits, and the Class 3 bits are mixed in an interleaving array of size 16x17 and interleaved over two slots in a manner that optimally divides each codeword between the two slots. At the receiver the coded Class 1 plus CRC bits, coded Class 2 bits, and Class 3 bits are extracted after de-interleaving. Maximum likelihood techniques using soft decision are employed to decode the Class 1 plus CRC bits as well as the Class 2 bits. The CRC is also used to further reduce the bit error rate (BER) of the subset of Class 1 bits over which it was applied by using generalized decoding techniques. In addition to the CRC based bad frame indication flag, raw channel bit error rate estimates for each codeword are also sent to the decoder as well.
